Thread: hp Officejet Pro 8720 scanner no longer functional

    Default hp Officejet Pro 8720 scanner no longer functional

    Hello everyone,

    a few days ago, after an update of Tumbleweed, all of a sudden the scanner of my hp Officejet Pro 8720 multifunction device was no longer functional. Xsane says "no devices available". I tried to reconfigure the scanner in Yast/Scanner, but the 8720 didn't appear in the list of supported devices any more. Printing on the same device is no problem.

    scanimage -L resulted in:

    No scanners were identified. If you were expecting something different,
    check that the scanner is plugged in, turned on and detected by the
    sane-find-scanner tool (if appropriate). Please read the documentation
    which came with this software (README, FAQ, manpages).

    [15:01:49.990738] [dll] sane_exit: finished

    This showed clearly that there was something wrong with /usr/lib64/sane/libsane-hpaio.so.1, which is actually a link to /usr/lib64/sane/libsane-hpaio.so.1.0.0.
    A little bit more investigation showed that in Leap 15.3 the scanner still worked. Copying the functional libsane-hpaio.so.1.0.0 from the Leap system to Tumbleweed fixed the problem.
    So there must have been introduced an issue with the latest version of hplip-sane of 9th May 2022.

    Could someone please explain to me how this bug should be officially reported? I could of course contact the developer being mentioned in the change log, but I don't think that is the preferred way.

    Regards,
    Armin

    I have exactly the same problem here, with my HP Color Laserjet Pro MFP M277dw.
    Prints without problem, but scanner is dead. I have it connected through the network, not directly. Don't know if it makes any difference.
    The printer does not appear anymore in the list of supported printers, though the HPLIP site reports it as supported... which is obvious, as I have used it for years.
